Muzhizha ra2019, analogue TV kutepfenyura kwakamira kushanda muRussian Federation. Yakatsiviwa neterevhizheni yemazuva ano yedhijitari yepasi . Ngatitarisei kuti odhiyo nevhidhiyo encoding uye tekinoroji yekufambisa inoshanda sei, izvo zvinokutendera kuti utarise akati wandei chiteshi kunyangwe mumakona asingasvikike enyika, funga kuti madhijitari eTV ma frequency ndeapi uye maitiro ekuamisa.

Channel Multiplexing

A multiplex inowanzonzi terevhizheni neredhiyo chiteshi zvakasanganiswa kuita imwechete yedhijitari block. Aya maTV neredhiyo akasanganiswa (multiplexed) uye anofambiswa kuburikidza neakakosha nzira yekufambisa. Pamudziyo wekugamuchira ( digital set-top box , digital tuner yakavakwa muTV), ivo vakaparadzaniswa (demultiplexed).
Panyaya yedhijitari yakawanda-channel terevhizheni, kutapurirana kunoitwa pane imwechete frequency. Iyo pasuru inogona kusanganisira chiteshi chemhando dzakasiyana uye mhando (SD, HD, 3D). Iwo anoumbwa neakasiyana masosi (TV neredhiyo makambani, vanoshanda, vanopa, nezvimwewo), nepo kutepfenyura hova, zvinyorwa zvidiki, teletext, TV gwara, nezvimwe zvichifambiswa.

Mutengo weiyo set-top box inosiyana kubva ku1 kusvika ku5 zviuru zveRubles, zvichienderana nekuvapo kana kusavapo kwemamwe mabasa mairi. Kuti ubatanidze kuTV yekare, chero DVB-T2 inogamuchira ine RCA inobuda (“tulips”) yakakodzera.

Mirayiridzo yekubatanidza:

1. Batanidza kubuda kwedhijitari set-yepamusoro bhokisi uye kupinza kweTV neRCA tambo. Batanidza antenna plug kune yakakodzera socket pane iyo DVB-T2 inogamuchira inogamuchira. Kana zvichibvira, isa antenna pedyo nehwindo uye woishandura ikananga kune terevhizheni.
2. Iyo antenna jack pane set-yepamusoro bhokisi inosarudzwa seRF IN, uye iyo RCA yekubatanidza pane ese ari maviri anogamuchira uye TV akanyorwa Vhidhiyo uye Audio. Kubatana kunoitwa zvakanyatsoenderana nekumaka kwemavara ekubatanidza zvinhu, zvisinei, kana iri nyaya yemadhidhiyo chiteshi, kuchengetwa kwayo hakuna kukosha. Iye zvino unogona kubatidza midziyo uye kuenderera kune iyo gadziriso.

Hardware setup

Kumisikidza terevhizheni yedhijitari kunouya pasi zvakanyanya pakutsvaga nekugadzirisa chiteshi. Ose ari mubhokisi-yepamusoro bhokisi uye muTV ine yakabatanidzwa DVB-T2 module, izvi zviri nyore kuita mune otomatiki modhi. Setting instructions:
